MASSACHUSETTS, A ooRPoRA'rou or MAssAoHnsETTs HANDLE-FEEDING MECHANISM FOR BRUSH-MACHINES. l

Application filed February 24, 1925. 'serial No. 11,091.

The present invention has for its object to provide automatic means for feeding handles of brushes orother similar articles to machines, which machines have an inlet belt or conveyor carrying pockets or cells within which the articles to be operated upon are loosely received. Heretofore the work performed by this mechanism has been done by hand and has, therefore, been a source of expense.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings:

Fig. 1 is a vertical section 1-1 Fig. 2) of the mechanism embodying our invention, the same being shown in con` nection with the endless chain of the machine with which it is employed.

Fig/2 is a top plan view of the parts shown in Fig. 1.

Fig. 3 is a section taken on line/S-S of Fig. l.

Figs. 4 and 5 are sections on line .1 -4, Fig. 3, to illustratethe different positions of parts of the machines. j v

Referring now to the drawings:

At is shown a conveyor inthe form of an endless belt or chain provided with a series of cells orcontainers B each ofwhich is open on the top as shown at C to receive a brush handle or back D, the same being loosely contained in the cell. vBeing open on the top the brush back can be dropped into the cell. I

In the drawings, we have shown the ma* chine as operating on tooth brush handles but it will be understood that it is capable of use in connection with articles of other forms. spout 11 to a vertical passage 12 in which they are stacked, as shown at 13.l The stack is located over the conveyor A at one end thereof and beneath the stack is a fixed sup@ port-ing plate 14 having a slot 8 which `is not in line with the stack. It Will, therefore, be seen, see Fig. 4, that the stack rests on a supporting plate 14 and cannot fall by gravity into'the cells'in the endless chain. At 15 is shown a slidev having a slot 9 therethrough which slot is of the size and shape (taken on lineV The brush handles pass down ay to permit one' of the brush handles to pass through it bodily. The slide is provided with a tail or guiding member 16 on'the underside of which is a lugll(w connected by a rod 18 tolinks 19. The forward ends of 'the links 19 are connected to arms 20 of a 60 `in registration with the slot 84 once while n l the shaft 25 moves the endless chain the width of one cell.r The bottom handle-in the stack 13 dropsinto the slot 9 in the forward end ofthe slide 15 and the stackthen rests on the plate 14. The forward movement of the slide 15 pushes one of the handles D out from under the stack, and the stack then rests on the slide `15, as shown in Fig. 5. Just as the slide lreaches they forward limit of its movement it `comes over the slot 8 in the plate 14 and the handle drops through into whichever cell B there happens to be below the slot 8. The slide then ret-urns to its former position and the operation is repeated.

`Since the handles are'slightly rounded on the edge', as shown in the figures, and sincev the slide 15 has a thickness exactly equal or slightly less than the thickness of the han- Y9o` dle, the slide does not strike any blow on the handlev and the machine operates smoothly and very. rapidly. l l l What we' claim is:v

of the character described comprising a continuously moving endless chain having a series of cells to receive the articles to` be fed, a stack for said articles, a rest for the articles in the stack interposed betweenthe im) n l l stack andthe endless chain and having a slottherein out of line with the stack but in registration with one of said cells, and a slide between the stack and the rest, said slide being'pmoved in time with the con- 105 veyor to register lin one position with the stack and in another position with the slot in the rest, the articles in the stack in said V1. The feeding mechanism for a machine second position being supported on the slide.

2. The feeding mechanism for a machine of the character described comprising a continuously movingendless chain having a series of cells to receive the articles to be fed'7 a cam rotatable in time With the movement of said endless chain, a stack for said ar ticles, a rest for the articles in the stack interposed between the stack and the endless 10 chain and having a slot therein, a slide between the stackfand the rest having a slot,

and means actuated by said cam to move the slide to bring the slot therein out of registration with the stack and into registration With the slot inthe rest.

In testimony Whereofvve' affix oursignatures. v
